An analytical method for the simultaneous determination of three restricted flavor additives(3-thujanone,camphor and safrole) in tobacco products by solid-phase extraction with gas chromatography-tandem mass spectrometry(GC-MS/MS)was developed and evaluated.The extraction conditions and MS conditions were optimized.Under the optimal conditions,three flavor additives had good linearities in the range of 10.0-500.0 μg/L,with correlation coefficients(r2) not less than 0.998 6.The limits of detection(LODs) and limits of quantitation(LOQs) for these additives were in the ranges of 2.3-5.8 μg/kg and 7.7-19.3 μg/kg,respectively.The average recoveries of three analysts were in the range of 74.9%-90.9% at three spiked levels of LOQ,1.5 LOQ and 2 LOQ,with relative standard deviations(RSDs) not more than 2.6%.The method is accurate,reliable and sensitive,and could satisfy the requirements for detection of three restricted flavor additives in domestic.
